We are using the above VPN to provide secure access to the network when
out of the office. Juniper have provided an application called Network
Connect which establishes the secure VPN tunnel between client device ie
laptop, PC and the office network.

The issue I have is that the Novell client (4.90sp2) doesn't always allow
you to login, sometimes it will login normally - map drives etc. Other
times it comes back saying can't find tree. If this happens you can still
map drives using the IP address of the server.

Has anybody come across something similar or this problem with Network
